Across all the personal computers of a comparable age and type to the ZBOX-OI520-P-U the maximum on-board graphics adapter memories range from 1GB to 16GB, and the average maximum on-board graphics adapter memory is 1.6GB.
Four USB 3.0 (3.1 Gen 1) Type-A Ports
Most computers of a comparable age and type to the ZBOX-OI520-P-U have between one and five USB 3.0 (3.1 Gen 1) Type-A ports, including the Zotac ZBOX-OI520-P-U which has four USB 3.0 (3.1 Gen 1) Type-A ports.
Zotac Desktop Computers Have Good Reviews
Zotac is one of the superior personal computer manufacturers according to average expert and user reviews, and Zotac also has good ratings for its few processor core computers.
Four USB 3.0 Ports
The Zotac ZBOX-OI520-P-U is a four USB 3.0 port desktop computer. Most of the other personal computers of this age and spec have between one and five USB 3.0 ports.
Has One Memory Slot
The number of memory slots found on the Zotac ZBOX-OI520-P-U is more than most similar spec desktop computers that have been around for around the same time as it. The most frequently found memory slot is 2x DIMM, but this memory slot is not found on this PC. The memory slots 2x SO-DIMM are also found on this desktop computer.
+3 More reasons for
The ZBOX-OI520-P-U is one of the narrower computers of this spec and age (only 154 millimeters) amongst comparable spec PCs of this age. The widths of desktop computers of this spec and age range from 3.4mm to 390mm.
The shallowest comparable spec personal computer that is a similar age to the ZBOX-OI520-P-U is 27mm deep and the deepest is 460mm. With a depth of only 154 millimeters, the Zotac ZBOX-OI520-P-U is one of the shallower similar spec PCs that have been available for more than two years amongst desktop computers of this age.
8 Reasons Against
Very Small Max Internal Memory Supported Processor
The smallest max internal memory supported processor of few processor core computers that were launched around the same time as the ZBOX-OI520-P-U is 4GB and the biggest is 32GB. At only 16 gigabytes, the Zotac ZBOX-OI520-P-U has a fairly small max internal memory supported processor compared to most of the other personal computers of a similar age and spec to the ZBOX-OI520-P-U.
Quite Slow On-Board Graphics Adapter Base Frequency
The ZBOX-OI520-P-U has one of the slower on-board graphics adapter base frequencies (only 200 megahertz) amongst similar spec personal computers of this age. Across all the computers that are a similar age to the ZBOX-OI520-P-U the on-board graphics adapter base frequencies range from 200MHz to 800MHz.
Quite Slow On-Board Graphics Adapter Dynamic Frequency
Across all the similar spec PCs that have been on the market for around the same time as the ZBOX-OI520-P-U the on-board graphics adapter dynamic frequencies range from 750MHz to 1,200MHz, and the average on-board graphics adapter dynamic frequency is 1,100MHz. At only 1,000 megahertz, the Zotac ZBOX-OI520-P-U has a quite slow on-board graphics adapter dynamic frequency compared to most of the other few processor core computers that were released more than two years ago.
Very Slow Processor Clock Speed
With a processor clock speed of only 1.6 gigahertz, the ZBOX-OI520-P-U has one of the slower processor clock speeds amongst desktop computers of this age. The slowest processor clock speed of PCs of a similar age and type to the ZBOX-OI520-P-U is 1GHz, the fastest is 3.9GHz, and the average processor clock speed is 2.9GHz.
+5 More reasons against
Only HDD Storage Medium
The storage speed of this computer is HDD, which is the most commonly found storage medium on few processor core computers that have been on the market for around the same time as it. A Hard Disk Drive (HDD) is the traditional storage method for computers. A HDD stores the information on magnetic disks. HDD drives are cheap, but they are slower than Flash and SSD bases storage systems.
If you want a computer with a faster storage speed then you might also want to look at the Shuttle DSA2LS (£148.75) (Flash).
Very Slow Hard Drive Speed
The Zotac ZBOX-OI520-P-U has a quite slow hard drive speed (only 5,400 revolutions per minute) compared to most of the other PCs that have been available for a similar time to the ZBOX-OI520-P-U. The hard drive speeds of comparable spec computers that were released around the same time as the ZBOX-OI520-P-U range from 5,400 RPM to 7,200 RPM, and the average hard drive speed is 6,900 RPM.
Quite Slow Maximum Turbo Frequency
At only 2.6 gigahertz, the ZBOX-OI520-P-U has a fairly slow maximum turbo frequency compared to most of the other personal computers of a comparable spec and age to the ZBOX-OI520-P-U. The maximum turbo frequencies of similar spec PCs that were released more than two years ago range from 1.8GHz to 5GHz.
Only Three USB 2.0 Ports
The ZBOX-OI520-P-U is a three USB 2.0 port computer. Most of the other personal computers of a similar age and type to the ZBOX-OI520-P-U have between one and nine USB 2.0 ports.
4 Other reasons to consider the Zotac ZBOX-OI520-P-U
Released Over Two Years Ago
This Zotac personal computer was released over two years ago.
Average Total Storage Capacity
The ZBOX-OI520-P-U has a relatively typical total storage capacity (500 gigabytes) compared to most of the other comparable spec computers that were released more than two years ago.
PCs with a bigger total storage capacity that might also be worth considering include the HP ProDesk 400 G1 (1TB).
Average Hard Drive Capacity
The ZBOX-OI520-P-U has a relatively standard hard drive capacity (500 gigabytes) compared to most of the other personal computers of a comparable spec and age to the ZBOX-OI520-P-U.
If you are looking for a bigger hard drive capacity then you might also want to look at the HP ProDesk 400 G1 (1TB).
+2 Other reasons
Average Internal Memory
At 4 gigabytes, the ZBOX-OI520-P-U has a pretty average internal memory compared to most of the other few processor core computers that were released around the same time as the ZBOX-OI520-P-U.
If you would prefer a bigger internal memory then you might also want to consider the DELL OptiPlex 3020 (£202.80) (8GB).
